About Us

We are a clinical-stage biopharmaceutical company that discovers, develops, and seeks to commercialize next-generation therapeutics for diseases representing significant unmet medical needs and burden to society, patients, and their families. Our current pipeline focuses on the central nervous system, respiratory, and metabolic diseases. We use a chemical genomics driven technology platform and proprietary chemistry to develop new medicines. Our pipeline currently has two drug candidates, RP5063 (brilaroxazine) and RP1208. Both are new chemical entities discovered in-house. We have been granted composition of matter patents for both RP5063 and RP1208 in the United States (U.S.), Europe, and several other countries.

Our lead drug candidate, RP5063, is ready for continued clinical development for multiple neuropsychiatric indications. These include schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), attention–deficit/hyperactivity disorder (ADHD), behavioral and psychotic symptoms of dementia or Alzheimer’s disease (BPSD), and Parkinson’s disease psychosis. Furthermore, RP5063 is also ready for clinical development for two respiratory indications — pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF). The U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to RP5063 for the treatment of PAH in November 2016 and IPF in April 2018.

On January 10, 2022, the FDA notified us that we may proceed with our Phase 3 trial for RP5063. On February 1, 2022, we announced that the first patients have been dosed in our Phase 3 RECOVER trial to assess RP5063 for the treatment of subjects with an acute exacerbation of schizophrenia. RECOVER is a global Phase 3, randomized, double-blind, placebo-controlled, multicenter study designed to assess the safety and efficacy of RP5063 in approximately 400 patients with acute schizophrenia compared to placebo.

Our primary focus is to complete the clinical development of RP5063 for the treatment of acute and maintenance schizophrenia.

Subject to the receipt of additional financing, we may also continue the clinical development of RP5063 for the treatment of BD, MDD, ADHD, BPSD, PDP, PAH and IPF. Moreover, subject to the receipt of additional financing, we may also advance the development of our second drug candidate, RP1208, for the treatment of depression and obesity.

Business Combination and Domestication

On December 14, 2020, our predecessor company, formerly known as Tenzing Acquisition Corp., a British Virgin Islands exempted company (“Tenzing”), and Reviva Pharmaceuticals, Inc., a Delaware corporation (together with its consolidated subsidiaries, “Old Reviva”), consummated the transactions (the “Business Combination”) contemplated by the Agreement and Plan of Merger, dated as of July 20, 2020 (as amended, the “Merger Agreement”), by and among Tenzing, Tenzing Merger Subsidiary Inc., a Delaware corporation and wholly-owned subsidiary of Tenzing (“Merger Sub”), Old Reviva, and the other parties thereto. Pursuant to the Merger Agreement, Merger Sub merged with and into Old Reviva, with Old Reviva surviving as our wholly owned subsidiary. We refer to this transaction as the Business Combination. In connection with and one day prior to the completion of the Business Combination, Tenzing re-domiciled out of the British Virgin Islands and continued as a company incorporated in the State of Delaware, and changed its name to Reviva Pharmaceuticals Holdings, Inc. Prior to the completion of the Business Combination, the Company was a shell company. Following the Business Combination, the business of Old Reviva is the business of the Company.

Old Reviva was incorporated in the state of Delaware on May 1, 2006 and its subsidiary, Reviva Pharmaceuticals India Pvt. Ltd., was incorporated on December 23, 2014. Tenzing was formed pursuant to the laws of the British Virgin Islands on March 20, 2018.

Implications of Being an Emerging Growth Company

We are an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, we are eligible for and intend to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including, but not limited to, (i) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, (the “Sarbanes Oxley Act”), (ii) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (iii) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements.

We will remain an emerging growth company until the earlier of: (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of Tenzing’s initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common equity held by non-affiliates exceeds $700.0 million as of the last business day of our most recently completed second fiscal quarter; or (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-public companies instead of the dates required for other public companies.

For a description of these reports and documents, and information about where you can find them, see “Additional Information” and “Incorporation of Certain Information By Reference.” Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business and prospects.

This prospectus and the documents incorporated by reference in this prospectus contain, and our officers and representatives may from time to time make, “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 that involve substantial risks and uncertainties, which include information relating to future events, future financial performance, financial projections, strategies, expectations, competitive environment and regulation.

Forward-looking statements are neither historical facts, nor should they be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

The foregoing does not represent an exhaustive list of matters that may be covered by the forward-looking statements contained herein and in the documents incorporated by reference herein or risk factors that we are faced with that may cause our actual results to differ from those anticipate in our forward-looking statements.

All forward-looking statements included in this prospectus and in the documents incorporated by reference in this prospectus are based on information available to us on the date of this prospectus or the date of the applicable document incorporated by reference. Except to the extent required by applicable laws or rules, we undertake no obligation to publicly update or revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

It is possible that some, or all, of the Investor Warrants may expire and never be exercised.

As of close of business on March 10, 2022, there were 15,133,286 shares of our Common Stock issued and outstanding and no shares of our preferred stock were issued and outstanding.

The additional shares of our authorized capital stock available for issuance may be issued at times and under circumstances so as to have a dilutive effect on earnings per share and on the equity ownership of the holders of our Common Stock. The ability of our board of directors to issue additional shares of stock could enhance the board’s ability to negotiate on behalf of the stockholders in a takeover situation but could also be used by the board to make a change-in-control more difficult, thereby denying stockholders the potential to sell their shares at a premium and entrenching current management. The following description is a summary of the material provisions of our capital stock. You should refer to our amended and restated certificate of incorporation and bylaws, both of which are on file with the SEC as exhibits to previous SEC filings, for additional information. The summary below is qualified by provisions of applicable law.

Voting. The holders of our Common Stock are entitled to one vote for each share held of record on all matters on which the holders are entitled to vote (or consent pursuant to written consent). When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast on such matter, except where a different vote is required by law, by the rules or regulations of any stock exchange applicable to us, or pursuant to any regulation applicable to us or our securities, or matters relating solely to the terms of preferred stock, in which case, such different vote shall apply. A majority in voting power of the shares entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders. Directors are elected by a plurality of the votes present in person or represented by proxy and entitled to vote.

Dividends. The holders of our Common Stock are entitled to receive, ratably, dividends only if, when and as declared by our board of directors out of funds legally available therefor and after provision is made for each class of capital stock having preference over our Common Stock.

Liquidation Rights. In the event of our liquidation, dissolution or winding-up, the holders of our Common Stock are entitled to share, ratably, in all assets remaining available for distribution after payment of all liabilities and after provision is made for each class of capital stock having preference over our Common Stock.

Preemptive and Similar Rights. The holders of our Common Stock have no preemptive or similar rights.

Redemption/Put Rights. There are no redemption or sinking fund provisions applicable to our Common Stock. All of the outstanding shares of our Common Stock are fully-paid and non-assessable.

Transfer Restrictions. Shares of our Common Stock are subject to transfer restrictions. Holders of our Common Stock may not transfer their securities unless (a) a registration statement is in effect under the Securities Act covering the proposed transfer and such transfer is made in accordance with such registration statement or (b) the securities are transferred in a transaction exempt from the registration requirements of the Securities Act and any related requirements imposed by applicable state securities laws. In the case of any transfer permitted under clause (b), the holder must notify us in writing of the proposed transfer and furnish us with an opinion of counsel, reasonably satisfactory to us, that the transfer will not require registration under the Securities Act or any applicable state securities laws. Each certificate representing a security contains a legend referring to this restriction on transfer and any legends required by state securities laws.

Continental Stock Transfer & Trust Company, located at 1 State Street 30th Floor, New York, NY 10004, is the transfer agent and registrar for our Common Stock.

We are authorized to issue up to 10,000,000 shares of “blank check” preferred stock, par value $0.0001 per share, with such designations, rights, and preferences as may be determined from time to time by our board of directors. Accordingly, our board of directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, conversion, voting, or other rights that could adversely affect the voting power or other rights of the holders of our Common Stock. The issuance of preferred stock could have the effect of restricting dividends on our Common Stock, diluting the voting power of our Common Stock, impairing the liquidation rights of our Common Stock, or delaying or preventing a change in control of our company.

If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the certificate establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:

The following summary of certain terms and provisions of the Investor Warrants is not complete and is subject to, and qualified in its entirety by the provisions of the form of Investor Warrant, which is filed as an exhibit to the registration statement of which this prospectus is a part. You should carefully review the terms and provisions set forth in the form of Investor Warrant.

The Investor Warrants entitle the registered holders to purchase Common Stock at a price equal to $4.125 per share, subject to adjustment as discussed below, immediately following the issuance of such Investor Warrants and terminating at 5:00 p.m., New York City time, on June 1, 2026.

The exercise price and number of shares of Common Stock issuable upon exercise of the Investor Warrants may be adjusted in certain circumstances, including in the event of a stock dividend or recapitalization, reorganization, merger or consolidation. However, the Investor Warrants will not be adjusted for issuances of shares of Common Stock at prices below its exercise price.

Exercisability. The Investor Warrants were exercisable immediately upon issuance and are exercisable at any time up to June 1, 2026. The Investor Warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of Common Stock purchased upon such exercise. Each Investor Warrant entitles the holder thereof to purchase 0.75 of a share of our Common Stock. Investor Warrants are not exercisable for a fraction of a share and may only be exercised into whole numbers of shares. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price and round down to the nearest whole share. Unless otherwise specified in the Investor Warrant, the holder does not have the right to exercise the Investor Warrants, in whole or in part, if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or 9.99% at the holder’s election) of the number of our shares of Common Stock outstanding immediately after giving effect to the exercise, as such percentage is determined in accordance with the terms of the Investor Warrant. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99% upon at least 61 days’ prior notice from the holder to us.

Exercise Price. The exercise price per share of Common Stock purchasable upon exercise of the Investor Warrants is $4.125, and is subject to adjustments for stock splits, reclassifications, subdivisions, and other similar transactions. In addition to the exercise price per share of Common Stock, any other applicable charges and taxes are due and payable upon exercise.

Warrant Agent; Global Certificate. The Investor Warrants were issued in registered form under a warrant agency agreement, dated June 1, 2021 (the “Warrant Agency Agreement”), between Continental Stock Transfer & Trust Company (the “Warrant Agent”) and us. The Investor Warrants were initially represented only by one or more global warrants deposited with the Warrant Agent, as custodian on behalf of The Depository Trust Company, or DTC, and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC.

Listing; Transferability. The Investor Warrants are not listed on any national securities exchange or other trading market. Without an active trading market, the liquidity of the Investor Warrants is limited. The Investor Warrants were issued in registered form under the warrant agency agreement between us and the Warrant Agent. Subject to applicable laws, the Investor Warrants may be transferred at the option of the holders upon surrender of the Investor Warrants to the Warrant Agent, together with the appropriate instruments of transfer.

Fundamental Transactions. If a fundamental transaction occurs, then the successor entity will succeed to, and be substituted for us, and may exercise every right and power that we may exercise and will assume all of our obligations under the Investor Warrants with the same effect as if such successor entity had been named in the Investor Warrant itself. If holders of our Common Stock are given a choice as to the securities, cash or property to be received in a fundamental transaction, then the holder shall be given the same choice as to the consideration it receives upon any exercise of the Investor Warrant following such fundamental transaction.

Rights as a Shareholder. Except by virtue of such holder’s ownership of our Common Stock, the holder of Investor Warrants does not have rights or privileges of a shareholder, including any voting rights, until the holder exercises such Investor Warrant.

The following summary of certain terms and provisions of the Pre-Funded Warrants is not complete and is subject to, and qualified in its entirety by the provisions of the form of Pre-Funded Warrant, which is filed as an exhibit to the registration statement of which this prospectus is a part. You should carefully review the terms and provisions set forth in the form of Pre-Funded Warrant.

The term “pre-funded” refers to the fact that the purchase price of our Common Stock in the Offering included almost the entire exercise price that will be paid under the Pre-Funded Warrants, except for a nominal remaining exercise price of $0.0001. The purpose of the Pre-Funded Warrants was to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, upon election of the holder, 9.99%) of our outstanding Common Stock following the consummation of this offering the opportunity to invest capital into our Company without triggering their ownership restrictions, by receiving Pre-Funded Warrants in lieu of our Common Stock which would result in such ownership of more than 4.99% (or 9.99%), and receive the ability to exercise their option to purchase the shares underlying the Pre-Funded Warrants at such nominal price at a later date.

Duration. The Pre-Funded Warrants entitle the holders thereof to purchase shares of our Common Stock at a nominal exercise price of $0.0001 per share, at any time until exercised in full.

Exercise Limitation. A holder does not have the right to exercise any portion of the Pre-Funded Warrant if the holder (together with its affiliates and certain related parties) would beneficially own in excess of 4.99% (or, upon election of the holder, 9.99%) of the number of shares of our Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants. However, any holder may increase, but not in excess of 9.99%, or decrease such percentage, provided that any increase will not be effective until the 61st day after such election.

Exercise Price. The Pre-Funded Warrants have an exercise price of $0.0001 per share. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our Common Stock and also upon any distributions of assets, including cash, stock or other property to our stockholders.

Warrant Agent; Global Certificate. The Pre-Funded Warrants were also issued in registered form under the Warrant Agency Agreement. The Pre-Funded Warrants were initially represented only by one or more global warrants deposited with the Warrant Agent, as custodian on behalf of DTC, and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC.

Transferability. Subject to applicable laws, the Pre-Funded Warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing. The Pre-Funded Warrants are not listed on any national securities exchange or other nationally recognized trading system, including the Nasdaq Capital Market. Without an active trading market, the liquidity of Pre-Funded Warrants is limited. The Pre-Funded Warrants were issued in registered form under the warrant agency agreement between us and the Warrant Agent.

Fundamental Transactions. If a fundamental transaction occurs, then the successor entity will succeed to, and be substituted for us, and may exercise every right and power that we may exercise and will assume all of our obligations under the Pre-Funded Warrants with the same effect as if such successor entity had been named in the Pre-Funded Warrant itself. If holders of our Common Stock are given a choice as to the securities, cash or property to be received in a fundamental transaction, then the holder shall be given the same choice as to the consideration it receives upon any exercise of the Pre-Funded Warrant following such fundamental transaction.

Rights as a Stockholder. Except as otherwise provided in the Pre-Funded Warrants or by virtue of such holder’s ownership of shares of our Common Stock, the holder of a Pre-Funded Warrant does not have the rights or privileges of a holder of our Common Stock, including any voting rights, until the holder exercises the Pre-Funded Warrant.

Anti-takeover Effects of Delaware Law and our Amended and Restated Certificate of Incorporation

Our amended and restated certificate of incorporation, our bylaws and the DGCL each contain provisions, which are summarized in the following paragraphs, which are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are intended to avoid costly takeover battles, reduce the Company’s vulnerability to a hostile change of control or other unsolicited acquisition proposal, and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire the Company. However, these provisions may have the effect of delaying, deterring or preventing a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including attempts that might result in a premium over the prevailing market price for the shares of Common Stock. Our amended and restated certificate of incorporation provides that any action required or permitted to be taken by the Company’s stockholders must be effected at a duly called annual meeting of such stockholders and may not be effected by any consent in writing by such holders unless such action is recommended by all directors of our board of directors then in office, except that holders of one or more series of Preferred Stock, if such series are expressly permitted to do so by the certificate of designation relating to such series, may take any action by written consent if such action permitted to be taken by such holders and the written consent is signed by the holders of outstanding shares of the relevant class or series having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting.

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which apply so long as the Common Stock remains listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of Common Stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved Common Stock may be to enable our board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise and thereby protect the continuity of management and possibly deprive stockholders of opportunities to sell their shares of Common Stock at prices higher than prevailing market prices.

Our amended and restated certificate of incorporation provides that our board of directors will determine the number of directors who will serve on our board of directors, subject to the rights of the holders of any series of preferred stock to elect additional directors. The exact number of directors will be fixed solely and exclusively by resolution duly adopted from time to time by our board of directors.

Our amended and restated certificate of incorporation provides that any vacancy on our board of directors, including a vacancy that results from an increase in the number of directors or a vacancy that results from the death, resignation, disqualification or removal of a director, may be filled only by a majority of the directors then in office, even if less than a quorum, subject to the rights, if any, of the holders of preferred stock.

Notwithstanding the foregoing provisions of this section, each director will serve until his successor is duly elected and qualified or until his earlier death, resignation or removal. No decrease in the number of directors constituting our board of directors will shorten the term of any incumbent director.

We are subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”). In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in the following prescribed manner:

Generally, for purposes of Section 203, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, owned 15% or more of a corporation’s outstanding voting securities.

Such provisions may encourage companies interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder. However, such provisions also could discourage attempts that might result in a premium over the market price for the shares held by stockholders. These provisions also may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our bylaws provide that at any meeting of our board of directors, a majority of the directors then in office constitutes a quorum for all purposes.

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation expressly authorizes cumulative voting. Our amended and restated certificate of incorporation does not authorize cumulative voting.

Our amended and restated certificate of incorporation provides that special meetings of stockholders may be called only by our board of directors acting pursuant to a resolution approved by the affirmative vote of a majority of our board of directors, subject to the rights, if any, of the holders of any series of preferred stock.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors. For any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received by the Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the one-year anniversary of the date of the preceding annual meeting of stockholders (for the purposes of the first annual meeting of our stockholders following the adoption of our bylaws, a stockholder’s notice must be received by the Secretary at the Company’s principal executive offices not later than (i) 90 days prior to the date of the first annual meeting or (ii) less than 10 days following the date the first annual meeting is publicly announced). Our bylaws also specify requirements as to the form and content of a stockholder’s notice. Our bylaws allow our board of directors or a committee of our board of directors to determine whether a nomination or any business proposed to be brought before a special meeting of the stockholders was made in accordance with our bylaws. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of us.

Our amended and restated certificate of incorporation and our bylaws provide that our board of directors, by the affirmative vote of a majority of our board of directors, is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, our bylaws without a stockholder vote in any matter not inconsistent with the laws of the State of Delaware. Any amendment, alteration, rescission or repeal of our bylaws by our stockholders requires the affirmative vote of the holders of at least a majority in voting power of all the then outstanding shares of stock entitled to vote thereon, voting together as a single class.

Our amended and restated certificate of incorporation provides that it may be amended, altered, changed or repealed in accordance with the DGCL.

Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to us or our stockholders, creditors or other constituents, (iii) action asserting a claim against the Company or any of our directors or officers arising pursuant to, or a claim against the Company or any director or officer of the Company with respect to the interpretation or application of any provision of, the DGCL, our amended and restated certificate of incorporation or our bylaws or (iv) action asserting a claim against the Company or any director or officer of the Company governed by the internal affairs doctrine will, to the fullest extent permitted by law, be solely and exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, any other court located in the State of Delaware with subject matter jurisdiction. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Company will be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation. However, it is possible that a court could find our forum selection provisions to be inapplicable or unenforceable. Although we believe this provision benefits it by providing increased consistency in the application of Delaware law in believe types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended; provided, however, that this provision will not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction.

We have shares of Common Stock and preferred stock available for future issuance without stockholder approval. We may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, to facilitate corporate acquisitions or payment as a dividend on the capital stock.

The existence of unissued and unreserved Common Stock and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third-party attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, the board of directors has the discretion to determine designations, rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each series of preferred stock, all to the fullest extent permissible under the DGCL and subject to any limitations set forth in our amended and restated certificate of incorporation. The purpose of authorizing the board of directors to issue preferred stock and to determine the rights and preferences applicable to such preferred stock is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with possible financings, acquisitions and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire, or could discourage a third-party from acquiring, a majority of our outstanding voting stock.

Our Common Stock and certain of our warrants that were issued in connection with our initial public offering, which we refer to as our Public Warrants (separate from the Investor Warrants and Pre-Funded Warrants that this prospectus relates to) are listed on Nasdaq under the symbol “RVPH” and “RVPHW,” respectively.

We will deliver shares of our Common Stock offered hereby upon exercise of the Warrants we issued in connection with the Offering. Each of the applicable forms of Warrant contain instructions for exercise. In order to exercise any of the Warrants, the holder must deliver to us or our Warrant Agent the information required in the applicable form of Warrant and the Warrant Agency Agreement, along with payment for the exercise price of the shares to be purchased. We will then deliver shares of our Common Stock in the manner described in the applicable form of Warrant and the corresponding Warrant Agency Agreement, copies of which are filed as exhibits to the registration statement of which this prospectus is a part.

Each Investor Warrant is exercisable into 0.75 of a share of our Common Stock, with an exercise price of $4.125 per share. Each Pre-Funded Warrant is exercisable into one share of our Common Stock, with an exercise price of $0.0001 per share.

Upon compliance by any holder with the instructions for exercise contained in the applicable form of Warrant and the Warrant Agency Agreement, we will, within the time allotted by the applicable form of Warrant and Warrant Agency Agreement, issue to the holder shares of Common Stock, free of a restrictive legend. Shares of Common Stock that are held by affiliates will be issued free of legend but will be deemed control securities

The validity of the securities offered hereby will be passed upon for us by Lowenstein Sandler LLP, New York, New York.
